. To all who-m it may concern."

Be it known-that'l, JOSIAH H. IIARVEY,

- a citizen of the United States residing at 4 :Scranton, in the countyfof'ibaclrawanna the hub which is fixed. to the telly and and State ofPennsylvania, have invented 'new and useful Improvements in Veh1cle-"Wheels, of which the following is a specification.

This invention relates to wheels, the object of the .inventionbeing 'toprovide a useful, n-ovel, practical and efhcient wheel for veh cles -111whlchiprovision is made for absorbing the jars. and vibrations impartedto the wheels in traveling over a rough surface and preventing thecommunication of such jar and vibration to the axles, runnln -gear andbody of the vehicles, the whedl embodying two hubs, normally concentric,

which are movable relatively to each other, the arrangement being suchthatythe hlibs of the wheel are yieldingly sustained in concentricrelation to each other and yet capable of'a perfectly free sliding and.relative rotati-ve movement.

- \Yith the above and other obje'cts in view,- the'nature of which willmore fully ap )ear asthe description proceeds, the invcn ion consists inthe novel-construction, combination and arran ement of parts as hereinfully described, illustrated andclaimed. v

Inthe accompanying drawings :-Figure l is a side elevation of a completewheel embodying the present invention. Fi 2 is a #5: similar view withthe adjacent sic e plates removed, showing" the interior hubs and"cushioning arrangement. Fig. 3 is a 1g metrical section through thewheel. 4 is an enlarged detail view of one'of the arms of the hubnext'to theaxle. Fig. 5 is a detail perspective view of one of therunners. Flg. 6 is a side elevation, showin the spring-arrangement and amodified .form of track. -Fig. 7 is a side elevation of one of thetracks having a removable section. yFig. 8 1s a detail cross sectionthrough tracks .on the line w m of Fi showing thesame constructedintegralli Fig. 9 1s a detail cross section on the line v -y of Fig. 7.Fig.f10 is a section similar to Fig. 8, showing the tracks andout'e'rhub formed se arately.

eferrlng to the drawin s, 1 designates the outer rim or felly of thewheel which may be provided with a tire 2 of'any usual or suitableconstruction. The spokes 3 are in Flg. 3.

-' connected at their outer ends to the rim or folly 1 and'are providedwith. enlarged and laterally extended bases 4 which are received inachanneled hub 5, the' said hub 5 being provided with side flanges 5between which the bases of the spokes are received, as shown Arrangedupon the inner side ofthe hub f) are arallel tracks 7. and 8 and in thepreierre embodiment of the invention, one of said tracks 8 is-fixed orstationary relative to the hub 5 while the othertrack 7 is maderemovable for the purpose of assisting in the assembling of thedifferent parts of the wheel as a whole. By reference to Fig. 3,

it will be seen that the track 7 is provided with a'marginal flange 9which is secured to the hub 5 by means of bolts -10 which alsopassjhrough the. enlarged inner ends .of the spokes thus securelyholding all parts together.

In addition to the parts abov'e enumerated,

the hub 5 comprises the op ositely arranged side platesll and these pates may-be 'secured to the flanges 6 of the'hub 5'by the same bolts 10above referred to. of the hub 5, spokes, and lt'elly herein abovereferred to'are rigidly connected together so as to move as a unitrelativel "to the inner hub next to the axle to be described.

The inner hub 12 which next to the axle iszpr'ovided intermediate itsends with a collar 13, which in the preferred embodiment'of theinvention is provided with a circularseries of threadedsockets 14adapted to, receive the threaded inner ends 15 of a shown in detail inFig. 4. These arms are preferablysquare n cross section as shown in Fig.4 and flClJflCGHt to their inner ends they" are provided with shoulders17 adapted 21. one of which is illustrated in'detail in Fig. 5. The body22 of each runner is provided with a square opening 93 adapted topermitthe squared arm 16 to sllde freely All parts series of radial arms16, one of which is therethrough and on its outer side each runnor isprovided with rollers Q-l which are feet in alinement.

adapted to roll and-travel in contact with the inner edges. of thetracks 7 and 8, above described, while permitting the pro ect1ng ends ofthe arms l6to move between and in contact with the inner surface'of thetracks 7 and 8 as clearlyindicated in Flg. 3, thus preventing lateralmovement. By squaring the arms 16 1n cross section, sai

arms are prevented from turnmg on the hub and they also prevent therunners 21 from turning. on

the arms, thus keeping all of the parts per The hub 12 also com I prisespreferably theoppositely arranged innerside plates 25 which as shown inig. 3, overlap'the' outer side plates 11 sufliciently to admit of alarge amount of relative play between the inner and outer hubs whileinclosing, concealing and protecting the springs and arms and runnerslocated be The plates referred to tween the plates;

. also exclude dirtand other foreign matter and keep the working partsof the Wheel in perfect condition. The inner side plates 25 are securedto and move with the hub 12 and form a part of the hub 12 of the wheel,

From the foregoing description, it will be seen that the two-hubs ofthewheel are ca'- pable offree relative rotative movement as well assliding movement between the tracks or in'the plane of the wheel asawhole, and that said wheel hubsnr'e sustained in concentric relation toe, 1.1."; by the circular series of springs under, the arrangementdescribed,

the said springs enabling one hub 5 ofthe wheel to slide relatively tothe other hub 12 while any relative lateral movementbf the hubs isprevented. A thoroughly bracedwheel is the result. I

Instead of making the tracks T and 8 continuous from their inner to theouter peripheries, each of'said tracks may be constructed as shown inFig. 6, where it will be observed that thetrackis cut away to leaveradial attaching extensions 26 which extend from the track properoutward to the hub 5, to-

which they may be secured in any convenient manner. One of the tracksmay be formed as an integral part 'of the hub 5, as shown in Fig, 3, orif desired, both of the tracks 7 and 8 may be formed as an integral partofthe hub 5, as shown in Fig. 8. It is also withinthe scope of thisinvention to form each of the tracks 7 and 8 separate from each otherand also separate fromthe. hub 5, as shown. at 26, 26 in Fig. 10.

When the tracks 7 and 8' are formed integrally with the hub 5, thestructure may be provided; at one side with a removable section 27 asshown in Figs. 7 and. 9, so that by removing said section, the arms'16and the runners 21 and the springs 19 may be applied one at a time tothe hub 12 and after all of said parts are in place and the construction of the hub 12 is completed, the 16%..

' provided with rollers ada movable section 27 may be replaced and securedby one of .the bolts 10 above referred to and as indicated in Fig.7.

It will be seen that 'the wheel as a whole comprises, an inner hub 12adapted to revolve freely on an axle in either direction,

and an outer hub 5 fixed to the rim or folly and mounted to revolvefreely. and completely in either direction around the innerhub 12,means'for holding the inner hub 12 and the-outerhub 5 laterallybracedfrela;

tively to each other without being attached to one another whilepermltting such relative rotative movement.

I While I have shown-and described the wheel in the preferredembodiment" thereof,

it will, of course,be understood that the gene eral designof the wheelmay be changed;

also that various changes may he made in the. form, proportion and minordetails of.

construction of the wheel without departing from the principle orsacrificing any of the advantages of the invention. f I cla m 1. Awhee'lcomprislng an outer hub, an
